Energy Minister Fergus Ewing will be grilled by MPs on the SNP’s plans for independence.
The Highland MSP is due to give evidence to the energy and climate change committee at Westminster on Tuesday. It is part of the select committee’s inquiry into the potential impact of Scots independence on energy markets and policy.
David Wilson, Scottish Government director for energy and climate change, is also expected to attend.
Alex Kemp, Aberdeen University’s professor of petroleum economics, is scheduled to give evidence as well, as is Jo Armstrong, professor of public policy at Glasgow University.
The inquiry is probing the value of future oil and gas revenues, if they would go to the Scottish Government post-independence, and the SNP’s proposed creation of an “oil fund”.
Household prices, and the effect on climate change targets and obligations, will be examined.
Global energy consultancy firm AF-Mercados said in written evidence this week energy bills could be three times higher in an independent Scotland.
E.on, a major investor in renewables and in the offshore industry, said in evidence it “would expect oil and gas taxation revenues arising from oil and gas production in Scottish waters to accrue to the Scottish Government after independence”.
The energy committee is just one of several groups at Westminster investigating the potential impact of Scottish independence.
